Kang JR, et al. - Researchers assessed 1649 primary reverse shoulder arthroplasty (RSA) implanted between 2009 and 2015 to delineate the burden of and also to recognize the evidence for reoperation following primary RSA. Only 0.55% of cases with infection or instability necessitated reoperation. They found that most of the humeral component complications were associated with a specific design flaw of 1 implant system. They recorded that RSAs performed for proximal humeral fracture sequelae frequently underwent reoperation due to instability or humeral component–related issues. Humeral component fracture for 1 particular implant, humeral loosening, dislocation, infection, and glenoid failure were the most common reasons for reoperation, each occurring at a rate under 1%.
